The Miami Dolphins have made a big splash via free agency by adding a plethora of quality pass-catching options for young quarterback Ryan Tannehill. However, we can count Omar Kelly of the Sun-Sentinel amongst those who see a drastic need to shore up their offensive line this offseason, since they lost Jake Long and are left with a number of mediocre options and a lack of depth.

"Fail to fortify the offensive line and everything General Manager Jeff Ireland has done this offseason to 'provide Tannehill more toys' will be wasted because a quarterback can't throw pretty passes without proper protection," wrote Kelly.

"The Dolphins offensive line isn't deep. The unit lacks top end talent with the exception of Mike Pouncey and 2012 Pro Bowler Richie Incognito. And few players fit the team's preferred scheme, which requires more athletic 300-pounders and less bulldozers like Incognito and [John Jerry]."

We can also count ESPN NFL Draft Insider Mel Kiper Jr. amongst those who see issues on the Fins O-line. That's why he gave them Alabama's D.J. Fluker with the 12th overall pick in his most recent mock draft:

Mel Kiper Jr.

"The Dolphins will shift second-year man Jonathan Martin to left tackle in the absence of Jake Long, but it leaves a pretty big talent deficiency at right tackle, and in Fluker they get a player who is ready to step in immediately. The Dolphins have made personnel upgrades in their passing game, but they don't want the problem to become protection or an inability to run the ball and create short-yardage situations where they can open up the playbook. They do need another pass-rusher, but Fluker makes sense."
